Cant connect Octopi to wifi after restarting the router


I had to restart my internet router now my pi 3 running octoprint wont connect to the home network.

I've reformatted the card several times and tried to reconnect. I've checked the network txt file, all details are correct. i cant access my home router because the ISP is crap and they cant give me the password to get into the router. my Pi has two red lights flashing, i can access the octopi.local via ethernet cable but that serves my no purpose whatsoever.

I'm using a mac OS, can someone help? i'm pulling my hair out here!!!



What does ifconfig wlan0 show?

Logs are pretty much necessary. The bootup log should be trying to connect, so review /var/log/boot.log.

Next, you can try taking wlan0 down and back up, then looking at the bottom of /var/log/syslog for more errors:

sudo ifdown wlan0
sudo ifup wlan0


do i type that in the terminal for mac OSX?


i'm running Octoprint 0.14.0

Does that have anything to do with it running on a Pi 3???


If you can connect to the Pi via ethernet, you need to log into the Pi and enter those commands on the command line. Are you familiar with how to "SSH" into the Pi to log on to it? (or you can temporarily attach a keyboard and monitor and connect that way)
